ROOF.

To all whomzi may concern:

Be it known that I, @Hennes A. STATLER, a citizen of the United States, residing at Qhica o, in the county of Cook and State A.of Illlnois, have invented. a certain new and useful Improvement in Roofs, of whichthe following is a full. clear, concise, und exact description, reference being hed to the accompanying drawings, i'ormingf e part of this specification.

My invention relates to improvements in roofs and has special reference to roofs constructed of iiexlble waterproof sheet roofing material commonly mede of a wool felt base im regnated with asphaltum or the like.

meng the several objects of my invention nre to provide a. System of rooting which shall result in producinlgr a bett-er and tighter roof .of the` class mentioned than has been possible be the methods heretofore in use; which of, considering its quality, shell cost less, and in which the various sheets composing the roof shall be so sealed together and the metallic fasteners so ar ranged that no water can seep or leak throu Th to the fasteners A urther object of my invention is to provide e roof made of flexible roofing innterinl. which shall be highly ornamental in appearance und which shall in general simulute nneurthen tile roof.

A further object of my invention is to provide :i roof construction, including the use of the roofin rmaterial in an elongated strip form. en( so secured by metallic fasteners thatthe fasteners are sealed beneath the roofing' material against contact with any water which muy f-all or collect` upon the roof.

A further object o( my invention is to provide :i roof of flexible material such as ready repnred roofingr in sheet form and eoveret with a grit materiel embedded in the asphaltunl material of which the rooting sheets are partly composed, the roof being so formed that the owing of Water or sliding of snow thereon is impeded suili eiently to materiell),7 assist in the preservation of the roof sind whereby the grit coat ingY is prevented from being washed oil", as occurs with ordinary roofs of this character.

A further object of my invention is to provide a roof of the charaeterdefined, hav- Patented Mnl'. 22, 1921.

ing ridges or steps and heaving,r colored grit embedded on its exposed surface to simulate earthen tile.

A further object ot my invention is to provide a roof construction whereby7 the use of sheet metal in the makingr oi the root', especially in the construction of gutters and the like. shall be eliminated to the end that the root shrill be more durable and more eheapl7 constructed than those commonly made.

My invention consists generally in a sys tem for covering u roof with waterproof flexible material in sheet forni, to make the roof waiter tight@ nud which includes the securing' of the top surface ot' the roofing material down upon the roof boards along one edge and then the turning: ot tlul ilexible sheets ove' and upon the secured edge or portion thereof` whereby the securing` metallic fasteners or nulle are eieetually covered and sealed from Contact with any water which may fall on or collect upon the roof.

My invention also consists in a system, as described` which results in an appearance quite similar to a tile root' but which is wind and" weather tight und of much less correv sponding weight and cost than a tile roof.

My invention also consists in u root of the` material described haring a series of transverse or horizontally disposed bullies, ridges, stops or dams, which impede the flow of water down the roof and serve to prevent snow slides.

M v invention also consists in the several features of construction and in the various arrangements und combinations of devices and parts whereby l ein enabled to attain the above mentioned and other objects und all as hereinafter described und particularly pointed out in the appended claims.

The present application is u division of in v rifipendin;r application tiled March 29, 1918. Serial No. 225.403 entitled Roofs, which has nurtured into Patent No. 133826Z April 2". 1920.

For si clear understanding of my invention; attention is directed to said accompanying: drawings, in which:

Fig. 8 is an enlarged vertical fragmentary* section on the line 8-8 of Fig. 1; and

Fig. 9 is a fra entary section of the preferred form of illisible roofing material.

Roofs, as usuall and commonl com structed of the flexible roofing material, are made of sheets of various sizes Vlaid and secured in overlap ing relation and providing substantially at roofs, or in other words, roofs having no ridges, projections, or ornamentation, except possibly printed or colored substantially fiat figures or lines formed on the roofing materiaL/ So ai' as I am aware no method of layin this ready-today exible roofing materia has so far been devised whereby the nie tallic fasteners such as nails are sealed beneath the roofin material against contact with water whic ma fall o n or collect upon the roof. Usua the securing nails are driven down into t e roof throu h the overlapping edges of the sheets an theirV heads are exposed to the weather, except for a possible coatin of asphalt paint or the like. In a few instances the nails or fasteners have been covered over by portions of the flexible material but not in a manner to seal the fasteners and the roof against the entrance or seepage of water through openings left in the flexible material, of

'which the roof is com osed.

As shown in Fig. 1, build the main part of the roof of elongated sheets or stri 1 of-the flexible material 2 is the ridge o the roof, 3 is the lower e ge or eave, 4 is the gable end and 5 is the hip-roll.

In constructin or laying the roof I first prefer to provi e a vertical edge board 6 for the cave to form with the roof 7 itself a space for the gutter, and in beginning the laying of the roofing material I first take a strip 8 of the roofing material and secure one edge of it to the upper edge of the board 6 by means of a clamping strip or bar 9 which may `have the form of a round rod as shown in Figs. 2 and 3. I secure this rod and the sheet 8 by nails 1() which I drive down through the rod the ed e of the sheet and into the upper edge of t e board 6. I then turn the sheet 8 'over the rod 9 and Y movement.

form it down into the angle between the edgeboard 6 and the roof to forni the gutter 11.` In thus turning the sheet 8 over I cover the nails 10 and the clamping rod 9. For temporarily holding the upper edge of the 'Io sheet 8 after it has beenturned over upon the roof, I secure it in position by nails 12.

Havin thus formed the utter, I proceed to t ie construction of t e roof itself and this I do in the manner best illustrated 'It in Fig. 3, the-upper edge of the first sheet having been secured as heretofore explained. I next arran e a second sheet 13 upon the first sheet an with its weather face in contact therewith(i as shown in dotted lines Fig. `8o

two sheets by means of nails 16, and whereby the edge 14 of the second sheet and the" ulpper edge of the lower sheet arefimly c amped together and held in fposition upon 9o the roof. It will be uiiderstoo that Vthe two weather surfaces of the' two sheets are in contact -beneath the strip 15 and that the it with which they are coated serves to Ebld them a ainst any possible relative 96 uithermorc the pressure caused by the nailing of the strip 15 upon the roof and the heating of the roof the sun finally causes the asphal'tic material of which the sheets are partly composed' to 10o soften and cfl'ectually seal the strips t0- gether along their secured edges below the clamping strip 15.

Having secured the edge of the secondV sheet upon the upper edge of the first sheet as described, I next turn the second'sheet up upon the roof over the strip 15, thereby covering the strip 15 and the nails 16, and proceed with further strips until I reach the ridge. Y,

The sheets 1 are thus secured alon their' horizontal edges and are sealed toget er by means of the strips 15 and nails 16 and the amalgamating of the materials of which the sheets are made so that the final product is a water ti ht roof having no openings through which water can seep or leak, even if the water stands n the roof to some appreciable depth... Furthermore, the use of the strips 15 and the turning of the flexible 130 material over these'strips rovides a roof having steps 17 of appreciable depth and the depth of the steps 17 can be made to simulate the edges of earthen tiles .which are usually about one-half to three-quarters 126 of an inch in depth attheir lower ed s, and

I preferably use a grit coating on t e roofing material in color similar to the color of tiles which it is desired to simulate.

A very valuable feature of my invention.130

resides in the fact that the construction lends itself particularly to the covering of, old shingle roofs because the strip 15 can be nailed securely in place above or upon the old shingles, pressing and holding them down tight, and the clamping strip provides a solid, firm and substautiall rigid foundation for the rooting sheets which avoids the Water catching hollows produced by nailing the sheets directly to the roof and particu larly when the sheets are secured on top of old shingles. Furthermore the space 18 beneath the rooting strips 1 leaves ample room for the old shingles without the detrimental feature of the forms of the old shingles showing through the finished roof. This particularly results from the fact that I make the strips 1 relatively narrow, to simulate tiles which are usually eight or nine inches in length, Aand consequently the weight of the strips 1 is not sufficient to cause them to conform with thel shapes of the shingles even if the roofing material becomes softened in summer by the sun.

lIn covering the two sides of the roof I run the upper edges of the last sheets up upon the ridge member 19, Fig. 2, 'and then I roceed to cover the ridge member 19 as fo lows: I take a long strip of the rooing material 20 and lay it upon the roof with one edge adjacent to thenridge pole 19 and se cure it 1n position by means of a wooden strip 21 and nails 22. I then secure a second wood strip 23 along the other edge of the roofing strip 21 with nails 24 and form the roofing strip 21 around upon and over the nails 24, as shown in F ig. 2, driving the nails 24 down into the root on the opposite side of the ridge pole. The nails 22 and 24 are thus' completely inclosed and protected against any moisture or water.

Another important feature of my improved roof is that the sheet 1, due to the softening influence ot the sun will settle down between the clamping strips 15, as shown in dotted lines Fig. 3, the clamping strips 15 and the lower edges of the roofing sheets 1, which are wrapped around same, forming ripples. baffles or dams on the roof which eiectually prevent snow slides, or thc rushing of the rain water down the roof at a speed to loosen or carry away the grit material with which I preferably cover the sheets l.

Preferably. as illustrated in Fig. 1, I make the flexible roong stri 1 long enou h to extendvthe whole length o the part of tIie roof whi'h am covering, so as to avoid, as far as pratticable, any vertically extending joint at the end of the strip between the vertically extending projections 25. purpose of sealing the roof against the entrance of water at the ends of the strips 1, I form the ends of the strips 1 upwardly, in the form of vertically extending flanges 30,

adapted to contact tightly with the side faces of the projections 25 as best shown in Fig. 4. These flanges 30 may obviously be nailed or otherwise secured to the side laces of the projections 25, but whether they are thus secured or not, they are held tightly pressed against the projections 25 by the U-shaped covering members 27 when these members are sprung down over the ridges 25 and over the adjacent upturned flanges 30 of the roofing strips 1.

An advantageous feature ot this structure is that while I may secure the several thereof and which nails are adapted to be covered by the next higher U-sha ed inember 27. I may omit these nails en yet hold these U-shaped members securely in place, because I make these U-shaped members 27 yielding or springy and I turn the covering within the side edges thereof. In consequence of this the grit covered or inner surface oi' the covering within. the U-shaped members 27 contacts directly with the rit covered surface of the llanges 3U, and w ien these members 27 have once been force down into place upon the projections 25, these two contacting grit surfaces interlock so tightly together that it is difficult to removethe members 27. This locking of the members 27`=in position eliminates any possibility o the wind lifting or loosening these members 27.

When the sheet 1 ends at the gable edge of the roof, I preferably cut the stri 15 a trifle short of the end of the roof, as st shown in Fig. 5, so that I can flatten down the overlying layers ofrrooin adjacent to the end of the roof, and then seal the ends of the several sheets 1 tightly to the roof by means of a. strip o wood 31 which I nail vertically on the roof, substantially flush with the end of the roof. -While the nailinr on of the strip 31 might be sufficient to seaI the ends of the strips 1 to the roof, I prefer to cover the stripV 31 with the roofing material, and thus not only rotect the strip 31 from the weather, but a so protect the nails with which the parts are secured, and also thoroughly seal the joint between the roof ing strips 1 and the roof base. purpose I prepare the strip 31 b securing pieces 32 of the flexible roofing rhaterial to the under side of the strip 31. After ther strip 31 has been nailed in place,

down on the outer end of the roof, securing them against the end of the roof by nails 33 and stripls 34 covered over by the strips 32 as best s own in Fig. 5, simi ar to the manner of' securing the strips 2O to the roof around the ridge 19.

In Fig. 8 I have shown an enlarihcrossll section of the clamping strip' 15. ile it I wrap thel i pieces 32 around the strip 31 and carry them For this 4 namens is possible to use other shapes oi"` strips I ends by vertically extendin narrow pro# 06 prefer to use strips having the edge 33 gestions the endof the roo n strips bent around which the roofing strips 1 are upwardly against the sides of said vertically 'it-1 www...
